Description from store
If you are a developer, you can use Tamper Dev to debug your websites, or if you are a pentester, you can use it to search for security vulnerabilities by inspecting the HTTP traffic from your browser.
Unlike most other extensions, Tamper Dev allows you to intercept, inspect and modify the requests before they are sent to the server, and before they are sent back to the browser interactively, and without any additional installed software.
How to use?
1. Press [ Alt ⌥ ] + [ T ] or click on the extension button
2. Filter the requests you are interested in
3. Enable interception, and trigger a new request
4. Modify all requests before they are sent to the server
5. Modify the responses before they are sent back to the browser

About Tamper Dev:
This is the new version of the extension previously called Tamper Chrome, but now supports multiple browsers, and does not require an auxiliary app. This extension provides functionality similar to Burp Proxy, MITM Proxy, OWASP ZAP, Tamper Data, and Postman Proxy Interceptor, but without the need of additional software, with full support of HTTPS connections, and trivial to set-up (just install).

- (2023-07-06) Rodolphe Breton: It simply works. Perfect tool.
- (2023-07-01) SG Apps: This extension is really helpful when you don't know to use something like Burp Suite!
- (2023-05-31) zhihan peng: very useful tool
- (2023-02-07) KNIGHT RIDERS BD GAMING: Very Good Extension
- (2022-11-09) Jarek Gołębiowski: You can change POST payload with this, nice! Like in old Tamper Data. Not sure how filter work, if I enter there URL it disappears, but main function works. I have also seen "...probably because of enterprise policies." but just ignored it.
- (2022-10-20) Ryan Mark Supremo: Nice extension, really helpful to my work
- (2022-05-27) Ryan Leach: Closing the tamper dev window upon refresh is needlessly annoying, and prevented me from interecepting xhr requests that occured before being able to open the extension.
- (2022-05-21) Jason Zhang: There are too much bugs in the extension, it can't catch all the request.
- (2022-04-02) Yufeng Lan: Very cool. Current limits: 1. Can't save filters and intercept rules for future use, compare with another ext. named Netify. 2. I guess reponse body is not decoded in utf-8, so that non-ascii chars displayed incorrectly.
- (2021-09-09) Aurelien Schiltz (Kangoo13): I am missing something or is there a big functionnality missing from the old Tamper Data ? I can't "deny" an http request that I don't want my browser to do after that I intercepted it. Except for that, the extension is cool.
- (2021-08-01) alaska Canyon: Failed to attach to - probably because of enterprise policies. chrome 92 work in incognito
- (2021-06-10) Abdul Wadood: Nice extension. Can we save the changes for future requests (on page refresh)?
- (2021-05-26) Juan Carlos R: Worked correctly for me, I haven't used it a lot but does its job!
- (2021-05-25) Waso Danilenko: doesn't work, "probably because of enterprise policies."
- (2021-05-17) Tian Chen: nice tool, but chinese messy code
- (2021-03-31) Phan “WEB ZONE VN” Tam: Works as expected!
- (2021-02-25) Aurélien P.: Thanks to the author, it's very easy to use and i like the design!
- (2021-02-20) Michael Vreeken: Works as advertised. Can't ask for much more.
- (2021-02-10) Teodor Narliyski: Failed to attach to xxx - probably because of enterprise policies. what?
- (2021-02-05) Eric To: There is no way to just intercept ONE request or intercept filtered request... it just intercept everything. In addition, I tried to intercept the production js file and replace it with a development version, but the file itself is quite large, so when you try to copy paste it into the response body, the whole thing freeze for a whole minute. The UI needs work too.
- (2021-01-21) Timur: I wanna say author - Thanks! Really cool extension with friendly UI and very useful functional. But you can do this app better, if you add supporting Cyrillic charset it will be awesome
- (2021-01-12) Michael Deming: very good app. good interface works well and overall a good app.
